Figures 13A and 14A show the first connector 100 and the second connector 200 in a mated and connected state, but the illustration of the first substrate 300 and the second substrate 400 are omitted, and Figures 14B and 14C show them Section structure. In addition, FIG. 13B is a partial enlarged view of FIG. 13A.

The second connector 200 is inserted into the first housing 50 having a square frame shape of the first connector 100 and is housed there. At this time, the upper ends of the outer wall portions 51, 52 of the first housing 50 facing the outer wall portions 51, 52 of the second substrate 400 are respectively formed with curved portions 51a, 52a, and therefore, the second connector 200 receives these curved portions 51a. , 52a can be inserted into the first housing 50 smoothly.

The positions where the gaps between the columnar portions 73a are almost filled can form a barrier between the terminals 41, 71 for high-frequency signals and the terminals 42, 72 for low-frequency signals.

The above is a description of one of the embodiments of the connector assembly of the present invention. According to this embodiment, the following effects can be obtained.

(1) "On the first housing 50 of the first connector 100 and the second housing 80 of the second connector 200, there is no arrangement: the conventional technology is formed by hollowing out the outer wall part around it The contact piece has a gap, so electromagnetic waves will not leak out from the gap, and the barrier effect can be improved compared with the conventional technology.

(2) "The structure in the state where the first connector 100 and the second connector 200 are fitted and connected to each other is: the first housing 50 and the second housing 80 in the shape of a square frame are arranged along the second housing 80, respectively. The entire length of the convex portions 81a, 82a formed by extending the sides of the outer wall portions 81, 82 of the first housing 50 contacts the outer wall portions 51, 52 of the first housing 50, and the curved portions 51a, 52a of the first housing 50 are based on their entire lengths. It is in contact with the outer wall portions 81 and 82 of the second housing 80. The curved portions 51a, 52a and the convex portions 81a, 82a, viewed from the mating direction of the first connector 100 and the second connector 200, are located partially overlapping but not completely overlapping, and are complementary to form a square frame In this way, most of the space between the first housing 50 and the second housing 80 will be in a state without gaps due to the presence of these curved portions 51a, 52a and convex portions 81a, 82a. Greatly improve the barrier effect. In Figs. 14B and 14C, the arrow b indicated by a dashed line represents a schematic state of electromagnetic waves intruding into the gap between the first housing 50 and the second housing 80. It can be seen from Figs. 14B and 14C that: because of the presence of Fig. 14B The presence of the curved portion 51a in FIG. 14C and the presence of the convex portion 81a in FIG. 14C can respectively prevent electromagnetic wave radiation from leaking out.

(3) "In addition, notches 55, 57 and cut-in grooves 58 formed on the lower end of the first housing 50 facing the first substrate 300 of the first housing 50; and formed on the second housing 80 facing the second substrate 400 The notches 84 to 86 at the lower end of the housing 80 and the partition 87 are buried by soldering, respectively. Therefore, it is possible to prevent electromagnetic waves from radiating and leaking from these places.

In addition, in this embodiment, the carrier cutting portion 51c is provided at a position on the upper end side of the first housing 50 of the first connector 100, and is formed on both sides of the carrier cutting portion 51c to enable cutting operations. The easy-to-use notch 51b does not have a curved portion 51a in this part, and the curved portion 51a cannot be used to seal the gap between the first housing 50 and the second housing 80. However, such a gap is acceptable. The convex portion 81a of the second housing 80 is closed as shown in FIG. 14B. That is, the depth of the notch 51b is set to a depth that does not hinder the contact between the convex portion 81a at the portion (position in the side direction) where the notch 51b is located and the first housing 50.

Therefore, in this embodiment, the carrier cut portion 51c is provided on the upper end side of the outer wall portion 51 of the first housing 50. If the carrier cut portion is provided, for example, on the lower end side of the outer wall portion 51, it will There is a problem that it is difficult to solder the first ground circuit pattern 310 of the first substrate 300. If the carrier cut portion is provided on, for example, an extension line in the side direction of the outer wall portion 52, it will be difficult to separate the two halves. The first housing 50 composed of the body is connected with each other. Therefore, it is better to provide the carrier cut portion 51c on the upper end side of the outer wall portion 51 in the manner disclosed in this embodiment.
